The object was the short distance transportation refrigerated truck, which belonged to current mainstream in Beijing. A computational model was established for solving the temperature field distribution of the refrigerated truck. The model took the wind speed at the air conditioning outlet, air temperature, cars wall and cargo area temperature of the refrigerated truck as the initial boundary conditions. The unsteady shear stress transport (SST) k-ω model of computational fluid dynamics (CFD) was used to simulate the temperature field distribution on different boundary conditions and stack methods in the refrigerated truck. Under specific boundary conditions with alternating the wind speed in the outlet and the cargo stack mode, the model could determine the best outlet wind speed and stack way of cargo through comparative analysis. The results showed that when the wind speed was 5m/s and stack methods was void in the middle and two sides, the temperature field distribution in the refrigerated truck was the best uniform. The tests showed that the simulated values were in a sound agreement with the measured ones and the average absolute error of the temperature was not higher than 1℃.
